However , compared with flat , its geometric shape is so specific and complex that need new way to adapt in ultrasonic testing 但由于相贯节点相比平板焊缝,其几何形状特殊和复杂,超声探伤时需要新的方法来适应。
It analysed the undt characteristic of the joint layer , summed up the wave amplitudes at different depth by statistic , and then presented the testing ways with ultrasonic . the results is showed as follows : 1 分析了结合面粘结缺陷的超声探伤特性，通过统计总结了不同深度结合面探伤的规律性，并在此基础上提出了结合面的探伤方法。
Researchers have tried several detect methods , and made some improvements . but there are still deficiencies . there are many difficulties in detecting flaw location because of the complex construction 长期以来,研究工作者进行了多种探伤方法的尝试,取得了一定的成绩,但是还存在一些不足,原因是相贯节点结构复杂,超声探伤时缺陷定位的困难很多。
This paper investigated the ultrasonic nondestructive testing ( undt ) problem on the bonded layer between wcu and cu ( or crcu ) , which is an ideal and widely used material for contact , by using digital ultrasonic testing device through design and manufacture appropriate reference blocks 本次实验通过设计和制作对比试块，利用数字超声探伤仪研究了烧结wcu cu ( crcu )结合面粘结缺陷的超声探伤问题。
Multiple used all conclusion of deduction , combined the result of the data in site , the choice of probe , and information of equipment , take face - to - object programme method , use visual c + + 6 . 0 to develop computer aid testing system of y tubular joints . through the system , it produced the result automatically and rapidly 综合所有的推导结论,同时结合现场数据,探头选择,仪器信息等方面的结果,采用面向对象的编程方法,利用visualc + + 6 . 0开发出了y型管节点超声探伤计算机辅助系统,通过该系统可以实现声束传播的模拟,自动快速地生成探测结果。
System synthetically uses digital ultrasonic flaw detection technique , computer technique , auto control technology and constructs intact hardware system ; constructs software system including complete locomotive wheel - set graphics base , diagnosis document database , checkout result database and smart analysis module by investigation , summarization , test , theory analysis etc . 为此，提出了机车轮对智能超声波探伤系统的总体方案，该系统综合利用数字超声探伤技术、计算机技术、自动控制等技术，构成完善的硬件系统。通过调研、总结、试验、理论分析等手段建立完善的机车轮对图形库、诊断文档数据库、检验结果数据库及智能分析模块等软件系统。
This result offers very easy method for the material analysis . application studies approve that the sensor has large application markets . the applications include the measurement of acoustic / vibration signal , intelligent material and intelligent structure , the measurement of hydro - acoustics , ultrasonic inspection and the measurement of current rate of fluid 传感器的应用研究实验论证了该传感器可应用于声振动信号的测量，智能材料和智能结构的声振动信号检测，水声检测，超声探伤以及流体流速的测量等许多方面。
